【摘要】 通过Mo与玻璃中氧化物的反应自由能计算,实验室试验及工厂中的大量生产实践探讨Mo在熔融玻璃中的稳定性能。除氧化铅玻璃外,Mo在熔融玻璃中作为电极材料及结构材料有足够的抗腐蚀性。Mo电极的腐蚀速度与玻璃液温度及电流密度成正比。Mo电极的合理的电流密度值为0.4—0.7A/cm~2。在使用一年后Mo变成粗大的再结晶晶粒组织。同时,氧含量由0.004增加到0.38wt%(最大值)。更多还原

【Abstract】 The free energy calculation of the interaction between molybdenum and theoxides in glasses has been correlated with the results obtained by immersing mol-ybdenum electrodes in molten glass bath in work’s practice. The corrosion rateof molybdenum electrode as observed was directly proportional to the currentdensity and to the temperature of molten glass, the critical current density beingabout 0.4-0.7 A/cm~2. After one year’s service in molten glass, the structure ofmolybdenum became very coarsely recrystallized, with an oxygen content of 0.04to 0.38 wt% (max). It would appear therefore, that molybdenum is sufficientlycorrosion-resistant to be adequately used as electrode or as structural materials inglass industry.更多还原
